I like Diamond perhaps more than I should (as I said last September). His stuff isn't overwhelming, and last season, for whatever reason, he didn't display the command of it that his numbers when pitching in the Atlanta system suggested.

Tuesday night, he had that command. Tuesday night he showed why the Twins took him in the Rule V draft and then traded a harder thrower to keep him.

It should be said, it's a lot easier to be a ground ball pitcher when your shortstop and second basemen can make plays. Diamond last year pitched a lot with Trevor Plouffe at short; he's had Brian Dozier behind him this year, both with Rochester and on Tuesday. That counts.

It's one start. But it is a start. I'm certainly more eager to see more of him than I am anybody else in the Twins rotation.
